"Is it possible to just return PagingState object without returning data?" --> No
Simply because before reading the actual data for each page of N rows, you cannot know at which token value a page of data starts... And it is worst than that, with paging you don't have any isolation. Let's suppose you keep in your application/web front-end the paging states for page 1, 2 and 3. Since there are concurrent inserts on the cluster at the same time, when you re-use the paging state 2 for example, you may not get the same results as the previous read. And it is inevitable in an eventual consistent distributed DB world On Mon, May 9, 2016 at 12:25 PM, Lu, Boying <boying...@emc.com> wrote: > dHi, All, > > > > We are considering to use DataStax java driver in our codes.
